`FRANKLIN W.- OHADBOURNE, OF FOND DU LAO, WISCONSIN. IMPLEMENTS TO BE USED` IN PLAYING DUPLICATE WHIST.

Specification of Letters Patent.

Patented Oct. 23, 1906.

To all whom t may concern:

Be it known that I, FRANKLIN W. CHAD- BOURNE, a citizen of the United States, residing at Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented new and useful Improvements in Implements to be Used in Playing Duplicate Whist, of which the following is a specification.

-- My invention relates to implements used in the playing of the game known as duplicate whist, in which a single deck of playing-cards is perforated and prepared in such a manner that a game of"duplicate whist of any'length may be played with the single deck instead of with a large numberof decks, as is usually required in the playing ofthe game; vand the object of my improvement 1s to so prepare and constructa single deck of cards that by a simple operation the deck may be quickly, easily, and accurately divided into hands for the playing of duplicate whist, which operation may be repeated a great number of times, each time the hands being different and yet so under control that any particular hand wanted for play in the return or duplicate plays may be obtained quickly, easily, andfaccurately. y

I attain the object of my invention by systematically perforating the various cards of a deck of playing-cards along certain lines, the perforations differing so far in alinement or in character or, design in predetermined cards that a pin or other instrument passed through any one of a number of sets ofy perforations and raised will select and lift out of place only'thosecards having `the peculiar alinement, character, or design of perforation distinctive of any particular hand.

The drawings hereto annexed and forming a part of this specification will assist in giving an entirely clear understanding of the invention, in which drawings- Figures 1 and 2 represent two of ,thereguvlar cards cfa deck as perforatedfor use according to the invention. Fig.l 3 represents one of the Hpersonal index-cards used for indicating the person to whom the hand separated belongs. Fig. 4 represents thefull deck of cards ready for play and with pin inserted for withdrawing the hand for player A No. 1 on hand No. 10, as indicated by the Ugeneral index-card placed on the side of the deck facing the operator.- Fig. 5 represents the-full deck of cards as inFig. 4, but with the pin forced through the deck sufficiently .farto raise above the balance of the deck the thirteen cards for player No. 1,- as above noted. Fig. 6 represents the same deck, the pin, however, having been withdrawn from the hole in which it was first inserted and inserted in a small perforation h near the edge of deck for the purpose of com- A i pletely separating said hand from the balance of the deck, the holes h in all of the cards of the pack being in alinement. Figs. 7 and 8 represent an edge and side view of the pin that may be used for removing the various hands from the deck. Figs. 9, l0, 11, and 12 are diagrams herein referred to and explained.

There are four of the so-called Hpersonal index-cards shown in Fig. 3 and numbered -l from 1 to 4 and so perforated as to always be raised from the balance of the deck with the first, second, third, and. fourth hands, respectively, there being four players, numbered from 1 to 4 before the game begins, and four personal index-cards numbered from 1 to 4; and since one of these four cards will always be separated from the balance of the deck with each hand of thirteen cards these personal index-cards will indicate the player to whom the hand y separated belongs, player No. 1 taking the separated hand having the personal indexcard numbered 1 with it, player No.2

taking the separated hand having the personal index-card numbered 2 with it, and

so on. In the drawings all of the cards are shown as on end,.excepting in Fig. 6, where they are .represented as arranged on their sides..

. The various regular cards of the deck, of which Figs. .1 and 2 and the raisedcard. the

`faceof which is visible in Fig. 6 are samples,

are numbered around the edgeA and perforated, each of the cards in the deck being both differently ,numbered and perforated, yet each being so systematically.. numbered and perforated that when the cards .are ar- ICO ranged with any one of the marginal` numbers on the upper side or rightend of each v I card in the deck, with said deck held asin Fig. 6, an insertion of. the pin in any one of the eighteen holes of the upper row, as indicated by the general index-card, will separate thirteen lcards from the balance ofv the ,f

deck; after which cards have been removed an insertion of the pin in the hole under that in which the pin was frstinserted will sepa-,` rate thirteen more cards from the balance .et

vthe deck; afterwhichcardshave beenfre- `moved an insertion of the pin in the holev under that in which the pin was inserted the now proceed to do.

second time will separate thirteen more cards from the balance of the deck, which balance will then consist of thirteen cards, making in all four sets of thirteen cards each for the' four hands necessary for one round or hand of whist. The removal of the cards above referred to is completed in each case by the withdrawal ofthe pin from the hole 1in which -iit is first inserted for the separation of any one of the four hands, then inserting it through one .of the small round perforations it near kthe edge of the thirteen cards separated, and, finally, by a lift completely separating such thirteen cards from the balance of the deck. Figs. 4, 5, and 6 will help to make this explanation clear.

Before proceeding further with a description of operating the deck it may be best Eto set forth fully the system of perforating `the various cards of the deck, which I will The perforations in the .cards are arranged in sets of from one to three perforations, there being eighteen of 'these sets of perforations on each half of the cards divided lengthwise, and the perforations are elongated. In other words, each `set of from one to three perforations with the spaces between them takes up but one-half of the width of each card in the deck. As before stated, each set of perforations consists of from one to three perforations, depending on whether the card is to be raised on the first, second, or third individual hand or left -to make up the fourth individual hand or set of thirteen cards. The first perforation in each set is placed either almost all a'bove or almost all below an imaginary line running lengthwise of the card, having respect to the position of the lcards as they are portrayed in Fig. 6, the small portions left either below or above in each respective instance being sufficient to voverlap the first perforations .on the balance of the cards sufficiently to allow t'heentranee of the pin, as illustrated. Referring to Fig. 6, if the .card is .to be raised above the balance the perforation is placed thus in relation `to said imaginary line, while if it is to be left in the deck it is placed thus 9. For instance, the thirteen cards to ybe raised and separated for the first player in any particular one of the eighteen sets have .each but one perforation in `that set, and thatone perforation is placed below the line of perforations in the balance of the thirty-nine cards. The thirteen cards to be raised and separated for the second player from the balance of the thirty-nine cards in the same particular one .of the eighteen sets have each two perforations, the first one having been placed above .the first line .of perforations, vas shown above, and the second .one being placed below the line .of perfor-ations in the balance ofthe .twenty-six cards. The thirteen cards to be raised and separated for the third player from the balance of the twenty-six cards in the same particular one of the eighteen sets have each three perforations, the first two having been placed above the first and second lines of perforations, as shown above, and the third one being placed below the line of perforations in the balance of thirteen' cards. The balance of thirteen cards have each three perforations in this particular set, each of said three perforations being placed above the three lines of perforations in the balance of the cards, and thus being never raised when this particular one of the eighteen sets of perforations is utilized. Each one of the eighteen sets of three perforations each consists in the whole deck of thirteen perforations in as many different cards arranged as above explained for the first player, twentysix perforations in thirteen more of the cards arranged as above for player No. 2, thirtynine perforations in thirteen more of the cards arranged as above for player No. 3, and thirty-nine perforations in the balance of thirteen cards arranged as above for player N o. 4. Thus each one of the eighteen sets yof perforations through one-half of each card in the deck being arranged in above system will enable the operator to separate the deck into four individual hands of thirteen cards each, and since each set of perforations is different, in that the cards are arranged differently in perforating in each of the eighteen sets, there can be eighteen different hands of whist, each hand consistingof four individual hands of vthirteen cards each, separated for play.

The next operation in the perforation of a deck is the perforation of the other half of the deck and ythe numbering of the kcards around the margin in order to multiply the combinations of hands obtainable. In perforating the other half ofeach card the fifty.- t'wo .cards of the deck are paired or arranged in twenty-six sets of two cards each. Each pair is now perforated as follows: The blank side or half of each card is perforated exactly the same as the side already perforated in the other card of the pair to which it belongs. By this operation the two cards in each pair will be the reverse of the other in so far as the perforations are concerned, or if one of the' cards ,of each pair were to be turned end for end .the two ,cards ,constituting each pair would be perforated exactly alike. Now by keeping the cards in the same position as they were in before the last half of each card was perforated,or, in other words, keeping the cards in such a position that the perforations in each card .of a pair will be the reverse of the other card of such pair, the deck will he so constituted Ithat by the use of the needle, as .explained Aelsewhere in the specification, thirty-six hands .of whist, .each consisting of IOS four individual hands of thirteen cards each,

will be separated for-play. This is true for the reasonl that the whole deck may be inverted and eighteen hands of whist separated by the use of the perforations on either half ofthe deck. Since each card in the deck has its opposite, by reversing the whole deck the p number and position of the perforations will I for end a number l is printed on the margin of each card and on the same side or end of each card when such cards are held as above indicated. After this is done, so long as the figure l appears on the same edge of each card in the deck when the deck is held in position for operation the same original thirty-six hands will always be removed by the use' of any one of the thirty-six sets of perforatio'ns, and of course if any one of the cards were turned end for end with the bal ance of the deck the combination would be broken and some one of the four hands in each hand of whist removed by the use of any set ofperforations would have but twelve cards and one ofthe others would have fourteen cards. Of course the deck may be mixed or shufHed as much as is wanted, but the same cards will always be raised if the cards are kept in proper position end to end by the use of the iigure .1 in the margin. Now following this explanation another step, it will be easily understood that if any one or more of the twenty-six pairs were reversed or placed end to end with the balance of the deck, the hands removed by the operation of the deck would all 'be diiferent from the thirty-six hands removed by the first combination, and yet all of the sets of perforations would remove four hands of thirteen cards heach, for the reason that when any particular Y card is placed end for end with the balance of the deck its opposite will also be turned to take its place. -Care must always be taken, however, to invert thecards'in their proper pairs and not singly, or the four hands by any particular set of perforations removed will not each of them contain thirteen cards. For instance, if five of the pairs were inverted or placed end for end with the balance of the deck there would be a change of ten cards in eachhand of whist, or, in other words, f

ten of the fifty-two cards would be in different individual hands of thirteen cards from what they were in the iirst instance, and if on this inversion of the iive pairs of c ards the whole deck was numbered on the same marrgin of each card this would then ive usa second combination of thirty-six whist for play, which could always be removed so long as the iigure 2 appeared on the same margin of each card inthe deck. In this same way the balance of the combination-numbers are placed on the margin of the cards,l there being scarcely any limit to the number of combinations obtainable, since twenty-six pairs'can Vbe placed in asv many different relations to each other as there are words capable of being obtained by the use of the English alphabet. Since each new `combination-number means thirty-sixA different hands of whist, the number of hands obtainable by this deck are practically unlimited.

A word now regarding the index-cards.

'The general index-card is perforated so that it will never be raised with any hand withdrawn, and each half of the card is perforated alike and each one of the eighteen sets of perforations on each half alike. of each of the individual index-cards, except vthat the individual index-card for player N o.

1 is so perforated as to be raised with the first thirteen cards removed on any one of the thirty-six sets of perforations in the deck. Individual index-card No. 2 is so perforated as to be always raised with the second indi-A vidual hand of thirteen cards removed on any one of the thirty-six sets of perforations in the deck, No. 3 with the third hand, and No. 4 (being perforated the same as the general index-card) always remains with the fourth individual hand of thirteen cards. Since these four individual index-cards are always placed at theback of the deck,they will always be behind the thirteen cards, and so cover the face of the last one of the thirteen cards from view, as well as indicate the player to which the individual hand belongs. It will make no difference whether' the perforations differ in alinement or character or design, so long as the pin acts upon the cards to select them as specified. It will be noted that the `pin need not be provided with the flat portion, since after its insertion in the perfora# tions it need only be lifted to make selections of hands, as specified.

In operating the deck as above the general index-card is always placed, as shown in Figs. l

This is also true' ands of IOO IIO

index-cards serve as well to shield from observation the cards withdrawn as to indicate the different players. It is immaterial in which order any of the cards, either the personal index-cards or the cards in the deck proper, are placed, since an insertion of the pin in the same hole will always produce the same thirteen cards with its proper personal index-card at the front for a shield and index.
